A commentary on “A novel soft rough set: Soft rough hemirings and corresponding multicriteria group decision making”

Abstract

Zhan et al. (2016) proposed a novel soft rough set called soft rough hemiring and researched its algebra properties, along with an application in group decision making. However, we found that some results or its proofs are incorrect. Thus, the purpose of this note is to point out Remark 3.9, Proposition 3.16's proof are incorrect, moreover Theorems 4.9, 4.12, 4.15, 4.18 whose proofs mainly based on Proposition 3.16 and Lemma 4.43 whose proof based on Remark 3.9 are also generally incorrect.
